CONCRETE CART.

Application filed December 8, 1920. Serial No. 429,217.

To all whom it may concern:

Be it known that I, AR rHUR P. RomNsoN, a citizen of the United States, and a resident of the city of Plainfield, in. the county of Union, State of New Jersey, have invented certain new and useful Improvements in Concrete Carts, of which the following is a specification.

The improvements relate to carts adapted to be operated by hand and to be used for conveying plastic concrete and similar substances.

Among the objects of the improvements are to produce a strong and effective cart of the character referred to, of simple and inexpensive construction which can be made principally of sheet metal stamped or otherwise formed, and to so construct the parts that they may, when not assembled, be nested and otherwise placed together in a relatively small and compact space, for transportation, storage, and other purposes.

Carts of this character are used to receive concrete when discharged from a mixing device, and are ordinarily pushed by hand to the place where the concrete is to be placed and there dumped. In an ordinary building or other concrete operation a number of these carts are employed, and when the work has been completed it is often necessary to store the carts and other apparatus or transport them to another place. The manufacturer also finds it advantageous to make up the parts in considerable quantities and to keep these parts in stock for the filling of orders, and when orders are received to ship them unassembled to the purchaser. It is also necessary for the user to ship carts to a distant point to be used on another job, and by forming the parts of the cart so that they can be placed together compactly for this purpose a great saving is effected. The carts are also subjected at times to rough usage, and parts frequently become bent or broken. Therefore by making the carts of interchangeable parts, and having each part so constructed and'arranged that it may be easily removed and replaced by a similar part delay on account of needed repairs is avoided, since it is only necessary for the user to keep on hand one or more extra parts to provide against such a contingency.

The improvements are illustrated in the accompanying drawings, in which Figure 1 -'one wheel thereof in vertical plane with the axleshown in vertical cross-section at one side; Figure 3 is an enlarged detail in side elevation of one of the axle collars of the cart; Figure 4.- is a vertical section of one of the Wheel hubs; Figure 5 is afront elevation v of four bodies and handles nested, with outer one broken away at one side.

The body 1 is formed of a continuous piece of sheet metal pressed or otherwise formed into a bucket having downwardly inclined sides and ends, the front end having a greater incline than the sides or the other end so that the contents may be easily dumped by raising the handle. Around two sides and front of the upper edge of this bucket 1 on the outside extends a band of sheet metal 2 terminating in the arms 3 projecting rearwardly'therefrom and connected at their outer ends by the handle 4.- This band is secured to the top of the bucket by means of rivets 5, and across the back edge thereof and 'se'cured', to both bucket and extending arms 3 by means of rivets is a cross strip 6 having ends 7 turned and placed against the said arms. The handle 4 is secured to the extremities of the arms 3 by means of a bolt 8 extending therethrough. The parts thus described when once made may remain intact, and, as shown in Figure 5, may be nested by placing one bucket the inside another.

I ing from the under side of the strip 2 downwardly, and having a collar 18 integral therewith registering with a hole in the bucket. The axle extends through these collars and through the bucket and is fixed thereto by means of a pin 19 extending through the outer part of the collar and the axle. By this construction the walls of the bucket are greatly strengthened, and the stresses and strains transmitted through the axle distributed to the plate 17 and the salvage strip 2.

In assembling a cart it is only necessary to place the axle in position and secure it by the pins 19, then pass the hubs over the ends thereof and secure them by means of the pins 16. A washer 20 is provided between the pin and the outer end of the hub.

What ll claim is:

1. A concrete cart or the like comprising in its construction a body in the form of a bucket having an open top and sides converging from top to bottom, said body being made of a piece of sheet metal, a rim on the outer sides of the body at the upper edge thereof, reinforcing hub plates on the outer sides of the body and extending down- Wardly from the rim, axles extending through said plates and wheels mounted on said axles at the sides of the body and above midheight thereof.

2. A concrete cart or the like comprising in its construction a body in the form of a bucket having an open top and sides converging from top to bottom, said body bev ing made of a piece of sheet metal, a rim on he outer sides of the body and at the upper edge thereof, reinforcing hub plates on the outer sides of the body and extending downwardly from said rim, an axle extending through said plates, and wheels mounted at the sides of theb'ody and above midheight thereof, and removable holding devices engaging said axle and preventing the said wheels from passing over the ends of the axles. I I

3. A concrete cart or the like comprising in its construction a body in the form of a bucket having an open top and sides converging from top to bottom, said body being made of a piece of v sheet metal, reinforcing hub plates on the outer sides of the body and extending downwardly from the release 1 top of the My, and wheels mounted at the sides of the body and above midheight thereof, an axle extending through said body and plates and beyond the same at both sides thereof, upon which said wheels are mounted, and removable holding devices engaging said axle and preventing the said wheels from passing over the ends of the axles, said axles being removably connected with the body.

4. A. concrete cart or the like comprising in its construction a body in the form of a bucket having an open top and sides converging from top to bottom, said body being made of a pieceof sheet metal, a relatively narrow rim along the upper outside edges of the body, and wheels mounted at the sides of the body and above midheight thereof, an axle extending through the said body from side to side above midheight thereof and a collar secured to the sonter sides of the body and through which said axles pass, a plate formed integral with the collar extending laterally therefrom and secured flatwise against the side of the body, said plate extending to the rim of the cart and having its upper edge beneath the 7 lower edge of said rim.

5. A concrete cart or the like comprising in its construction a body substantially in the form of a bucket, with sides uniformly inclined inwardly from top to bottom on all sides and made of a single piece of sheet material, hub plates secured to the outside surface of the side walls, an axle extending through thevside walls and said hub plates and wheels removably mounted on the ends of the axle.

Witness my hand this 12th day of November, 1920, at the city of New York, in the county and State of New York.
